jpountz opened a new issue, #12956: URL: https://github.com/apache/lucene/issues/12956
### Description #12895 highlighted that our backward compatibility tests could use some love. I reviewed what we have and tried to collect a list of things we should improve: - [ ] Add backward indexes created with `BEST_COMPRESSION`. Currently, all indexes we create use the default `BEST_SPEED`. - [ ] Restore write logic of old FST versions. #12908 added support for the last version back, but there are older versions we should add back as well so that we can test them properly through `BasePostingsFormatTestCase`. - [ ] Restore write logic of old BKDWriter versions. Likewise, but for BKD trees. Restoring them would allow us to test them through `BasePointsFormatTestCase`. - [x] Add tests with real data to `BasePostingsFormatTestCase`. (done via #12925) - [x] Add tests with real data to `BaseStoredFieldsFormatTestCase`. #12927 -- This is an automated message from the Apache Git Service.
